According to a recently released survey, the NFL offers its paying customers the worst game day experience of the major U.S. professional sports.Which really confuses me, because every time cameras show the owner’s box during televised NFL games, it looks like people are having a great time despite their inability to execute a simple man-hug, let alone a high five. Yes, I’m looking at you, Chris Christie.The survey, conducted by the Temkin Group, focused on nine live-event experiences — select and purchase tickets; parking; enter arena or stadium; find your seat; use the bathroom; purchase food; purchase souvenir; watch game; leave arena or stadium; and open a line of credit to buy two beers.OK, we made that last one up. The biggest gripe across the sporting spectrum: parking.Of the nine criteria, the NFL placed dead last in eight. Other sports in the survey included MLB, NBA, NHL, NASCAR, PGA, MLS, WNBA and ATP.Personally, I thought the NFL game day experience was at its zenith when the Raiders featured Del Courtney’s band and the 49ers had juggler Ray Jason performing on the sidelines. The experience began degrading when the Rolling Stones’ “Start Me Up” began to blast… in… every… stadium… on… every… kickoff.The survey had a silver lining for the NFL. Pro football, it turns out, is the most popular sport to watch on TV. And why wouldn’t it be when you can park in your driveway for free?There was other data associated with the report. It can be found on the Temkin Group website available for purchase from $195 to $2,995.Let me know what you find out.
